Application March 6, 1939, Serial No. 260,204

3 Claims.

The invention relates to footwear heel plates and more especially to a non-skid heel for boots, shoes or the like.

The primary object of the invention is the pro-' vision of a heel of this character, wherein the same is constructed with calks and is susceptible of convenient fitting with the outer heel lift of footwear so as to assure against slipping on ice, slippery surfaces or otherwise in the wearing of the boot, shoe or the like.

Another object of the invention is the provision of a heel of this character, wherein the same is of a kind that will enable quick detachment so that when the heel becomes worn or otherwise unsatisfactory for service, replacement thereof can be had with dispatch, the non-skid part or element being of novel construction and is fitted at the heel end of a shoe in a novel manner.

20 A further object of the invention is the provision of a heel of this character, which is extremely sim'ple in its construction, thoroughly reliable and efiicient in operation, readily and easily attachable to and removable from the heel end of a shoe, being for non-skid purposes when in use,

strong, durable, and inexpensive to manufacture and install.

With these and other objects in view, the in- 3 vention consists in the features of construction,

combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and 35 pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a fragmentary elevation of a shoe of conventional form showing the device constructed in accordance with the invention apo plied thereto, the heel area of the shoe being partly broken away.

Figure 2 is a plan view of the heel plate per se.

Figure 3 is a fragmentary plan view looking toward the heel area of the shoe with plate removed.

- Figure 4 is a fragmentary rear and elevation with the heel plate in place. .1

Figure 5 is an exploded perspective view of the elements of the invention.

50 Similar, reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates generally a portion of a boot, shoe or the like, being of conventional form having an' outer wearing position.

rubber heel lift l0 joined in the usual manner to the heel area I I for the boot or shoe.

Formed at the longitudinal median of the outer lift i0 is a dovetail shaped groove I! which opens through the rearmost edge of said lift at 5 one end thereof while the opposite end is closed and is removed from the front end of said lift i0. Fixedly held within this groove I2 is a dovetail shaped bushing [3 of metal having opening through the outer side thereof a substantially T-shaped slot H, which at the opening side thereof is tapered in one direction, as at l5, and this open side of the slot -=is outermost when the cleat I 3 is fixedly held within the lift l0.

Matching the outer lift I0 is a heel plate [6 having projecting from the outermost face thereof spurs or calks I! while on the innermost face of this plate is fixed a key l8 of corresponding shape to the slot l4 and is removably fitted therein for wedging engagement with the bushing l3 so that the plate It, which is preferably of metal, is worn at the outermost side or face of the lift ill, the spurs or calks I! being for the purpose of preventing'slippage when walking over ice or slippery surfaces in theuse of the boot or shoe.

The plate I6 can be readily detachedfrom the lift ill on removal of the key I8 from the slot i4 accommodating the same within the bushing l3, which is-permanently worn within the lift ill.

The slot M with respect to the tapered formation of the open side 15 thereof is directed in a forward direction for the lay of the taper formation in this direction of the open side of said slot so that the key l8 can be freely inserted within the slot [4- from the rear of the boot or shoe and when the key I8 is driven therein it will be frictionally held in a secure manner for retention of the plate I6, preferably made from metal, in

What is claimed is:

1. The combination of a resilient outer heel lift having a slotted bushing therein, a plate for matching the heel lift, and a key permanently held on the plate and engageable in the slot in the bushing for separate fitting of the plate in -matched relation to said lift.

outwardly from the .plate in its matched relamatched relation to said lift, and calks extending tion to the said lift. outwardly from the plate in its matched relation 3. The combination of a resilient outer heel to the said lift, the said slot having a tapered I lift having a slotted bushing therein, a plate for i opening side thereto and the key correspondingly 5 matching the heel lift, a key permanently held tapered for a portion thereof with respect to l on the plate and engageable in the slot in the said entrance open side of the slot bushing for separable flttin: of the plate in JOHN W.
